sorry, I think I'm wrong here, I got curios and had a look at the
lilo.conf man page ( sorry, cheating).
so to be short :
image= /mount_point_of_your_RH_boot/linux_kernel #your image
   root=/dev/hda3 # that's your RH root directory ( / )
   label= Red Hat Linux
....
and the append above is actually duplicating the root lilo directive.

Possibly when you where configuring lilo before, lilo couldn't actually
find your kernel file, it needs it. It does some clever stuff with it. I
don't worry too much that it is not where Red Hat will look for it.
